ABSTRACT:
An improved system for producing a three-dimensional object from a fluid medium is described. The fluid medium includes an epoxy-functional silicon-containing monomer or oligomer, and a suitable cationic photoinitiator. The medium is used in a stereolithographic apparatus, which converts computer-generated data for the desired part to a real three-dimensional part, via the directed action of a laser beam or similar energy form on the liquid medium. This invention also embraces a method for producing the three-dimensional object from the liquid medium, utilizing a family of epoxy-functional silicon-containing materials.
